Fronius USA’s Stand-Alone Inverter Boosts Solar Efficiency

Solar power discussions typically center on the solar cells, but the inverters are an equally important aspect of energy conversion. Fronius USA’s IS 30 stand-alone inverter accepts a nominal battery voltage of 24 or 48V and supplies a nominal output of 2,200 VA at a maximum efficiency of 93 percent. The inverter weighs only 18 lb, so it’s practical to connect them together in parallel or in multi-phase operation even in constrained home applications. One factor in its high efficiency is the control architecture managed by Microchip Technology Inc.’s dsPIC digital signal controllers. Fronius exploits the 30-MIPS chips, which include counter-based PWM modules and analog circuitry.
